Abstract
In the United States, routine vaccination rates have plummeted across all age groups due to the COVID-19 pandemic, with our most vulnerable and under-served populations suffering the greatest declines. Returning to a “new normal” and recovering our nation’s health and economy is of the utmost importance; however, there is a critical need to recover and protect communities against the spread of other vaccine-preventable diseases and outbreaks. While routine vaccination rates are slowly recovering for certain age groups, the introduction of COVID-19 vaccines adds complexities and challenges to recovery efforts. If not addressed, hard-won gains in routine vaccination may be lost, which could result in communities missing out on the social, economic, and health benefits offered by vaccinations.
There is an urgent need to utilize evidence-based and innovative strategies to support both immediate and long-term efforts to recover, maintain, and sustain routine vaccination. Key short-term strategies include leveraging digital and mainstream media to drive awareness, coordinating across health and education sectors, utilizing centralized reminder recall, expanding access points to vaccination services, and elevating trusted voices for vaccination. In order to build back stronger, long-term strategies include enhancing immunization information systems, mitigating financial barriers to vaccination, investing in building vaccine confidence, and ensuring sustainable funding for immunization infrastructure.

INTRODUCTION
The COVID-19 Pandemic is a Critical Reminder of the Importance of Vaccination1
To help end the COVID-19 pandemic, individuals across the United States, from government officials to frontline workers, are engaged in a tireless effort to ensure Americans have access to and are vaccinated against COVID-19.2 Ending the pandemic is mission critical; however, it is also essential to build back stronger by developing and implementing measures to recover from subsequent public health consequences of the pandemic.
One such consequence is the severe disruption to routine vaccination services, resulting in considerable deficits in vaccination rates across all age groups.1,3,4 Vaccination is a global health and development success story.4 In the United States alone, routine childhood vaccination has been estimated to prevent approximately 42,000 deaths and 20 million cases of disease, averting an estimated $76 billion in total societal costs—in a single birth cohort alone.5
Disruptions to routine vaccination services have been recorded throughout the pandemic. Private claims data from 3 routine childhood vaccines, measles-mumps-rubella (MMR), diphtheria, tetanus, and acellular pertussis (DTaP), and polio suggest that an estimated 9 million doses may have been missed in 2020—and up to a 26% drop in those 3 vaccines between January and September of last year.6 An analysis from 10 state immunization information systems (IIS) estimates more than a 60% decline in MMR for children aged 2 to 8 years, and over a 60% decline in human papillomavirus (HPV) vaccination for adolescents aged 9 to 12 years from March-May of 2020 compared with March-May of 2019.7 These disruptions are attributable, in part, to social distancing measures, reallocation of health care workers, de-prioritization of routine health care services, and concerns that patients and caregivers seeking routine preventive services, like vaccinations, may be exposed to COVID-19.8,9
Local accounts from across the United States further demonstrate the magnitude of impact. Reports from New York City indicated over a 90% drop in vaccine doses given to children over 2 years of age between March and May of 2020.10 Colorado experienced similar troubling trends with a decline in vaccination rates of 31% for individuals aged under 2 years, 78% for individuals aged 3 to 9 years, and 82% for individuals aged 10 to 17 years between January 2020 and May 2020.11 These significant declines in vaccine coverage rates (VCRs) put our communities at risk for additional vaccine-preventable disease outbreaks and, in the case of HPV vaccination, additional cases of HPV-related cancers later in life, further straining a health system already fatigued from managing the COVID-19 pandemic.
The COVID-19 pandemic has also exacerbated existing health disparities and highlighted the need to focus on vaccine equity. When examining the decline of routine vaccination services, the consequences of the pandemic have had a disparate impact on underserved populations. Public childhood non-influenza vaccine doses were down by 11.2 million at the start of 2021.12 Data from the Vaccines for Children program, serving primarily children who are insured through Medicaid, uninsured, and underinsured, reported declines for HPV vaccination (21%), tetanus, diphtheria and acellular pertussis (Tdap) vaccination (22%), and meningococcal vaccination (18%) for 2020-2021 as compared with 2019.12 Traditionally underserved populations, such as those who are insured through Medicaid, have not only seen the greatest decline in routine vaccination rates, but are also are recovering at a slower rate compared with those with private insurance.13
Examples of Promising Efforts Underway to Support Routine Vaccination
The road to recovering routine vaccination rates requires cross-sectoral, concerted efforts to raise awareness of the importance of vaccination and to develop strategies to improve access to services. To address these challenges, actors across multiple sectors have taken action to address the declines in routine vaccination rates by implementing promising efforts to meet community health needs.
To raise awareness of the declines in routine vaccination, local and state health departments, Medicaid programs, commercial health plans, medical societies, nongovernmental organizations, the federal government, faith-based communities, community-based organizations, and others have implemented different strategies.7,14-19 “Calls to action” have been issued by leaders within the public health, cancer, and education communities. This includes an urgent action statement from the National Cancer Institute (NCI) that highlighted concerning declines in HPV vaccination coverage rates. The Centers for Disease Control and Prevention (CDC) released guidance about the importance of maintaining routine vaccination during the pandemic, emphasizing that vaccination services are essential health services that should be continued across the life course.3,20 The CDC’s Director of the National Center for Immunization and Respiratory Diseases (NCIRD) even issued a call to action urging all stakeholders to focus efforts on reversing the collapse in adolescent vaccination.3
National organizations, such as the American Academy of Pediatrics, launched campaigns to remind patients and families of the importance of returning to their health care professionals for routine vaccinations.21 Similarly, states are encouraging patients and families to receive routine vaccinations through locally tailored campaigns, such as the Michigan Department of Public Health’s “Be A Hero–VACCINATE” campaign, California’s “Don’t Wait Vaccinate” campaign, and the “Vax to School” campaign in Washington State.22-24
Enabling Equitable Access to Vaccination Services is Key to Recovering Routine Vaccination Rates
The COVID-19 pandemic has accelerated the adoption of telehealth options for select health services, which has changed how vaccination is recommended. Several state Medicaid programs released guidance for telehealth services recommending that health care professionals inform beneficiaries of any vaccinations that would normally be administered and encourage patients to schedule a time to administer routine vaccinations in person.25-27 With the increase of telehealth, however, certain populations are at risk for being left behind due lack of access to the Internet and digital illiteracy, highlighting the need for multiple care delivery models.28
Local hospitals and health systems have implemented innovative care delivery models to recover routine vaccination rates, such as mobile clinic vans and drive-through vaccination options.29,30 For example, Walter Reed National Military Medical Center was the beta site for innovative drive-through vaccination clinics.31 As innovative models try to meet patients where they are, practices deployed for COVID-19 vaccination should be considered for routine vaccination too. Partnerships have emerged between large health systems and community health organizations to build vaccine confidence and provide vaccination services at a convenient time and accessible location for COVID-19 vaccinations, leading to success in delivering vaccinations to traditionally underserved populations.32 Models of community-academic partnerships can be expanded and replicated for routine vaccination services to ensure vaccine equity in recovery efforts.33
Federal agencies have also taken action to increase awareness and expand access to routine vaccination and address vaccine confidence.34 Recently, the Biden administration made an investment in the vaccine ecosystem by dedicating $1 billion to build vaccine confidence, support vaccine education, improve vaccination rates for COVID-19 vaccines, as well as other vaccine preventable diseases, and support recovery of routine vaccination rates.35 The administration also made an additional $6 billion investment in community health centers to expand access to COVID-19 vaccines in underserved communities—in part through addressing vaccine hesitancy. Although directed toward COVID-19 vaccination, this infusion of funds has the potential to provide infrastructure support that could benefit the broader vaccine ecosystem. In addition, $500 million has been allocated to support school nurses for COVID-19 vaccination efforts as COVID-19 vaccination eligibility expands to younger populations.36 These federal actions are first steps to recover vaccination rates, but vaccination rates did not reach all target goals before the pandemic. Sustained investment in the vaccine ecosystem and health infrastructure is necessary to not only recover routine vaccination rates, but also improve them.
Short- and Long-Term Measures to Recover Vaccination Rates
Even with these and other promising efforts underway, recovering from the decline in routine vaccination rates caused by the pandemic will take years.3 This recovery requires all stakeholders to drive awareness of the importance of routinely recommended vaccinations, facilitate access to vaccination, and build vaccine confidence.
There are measures that can be taken now to support recovery in the short term as well as actions that can be taken to help achieve and sustain high vaccination coverage rates, build a more resilient vaccine infrastructure, and build back stronger.
In the short term, taking immediate action to recover routine vaccination coverage rates is necessary to help mitigate the future effects of the pandemic. Short-term strategies that should be implemented now include:
Leverage digital and mainstream media to drive awareness37
∘ Share information via e-mails, newsletters, and social media from trusted messengers detailing the importance of protection from vaccine-preventable diseases
Coordinate across health and education sectors3,38
∘ For populations like adolescents, who are currently eligible to be vaccinated for COVID-19, thoughtful planning is essential to ensure that they receive both COVID-19 vaccination as well as their routine and catch-up vaccinations
∘ Partner and coordinate with school leadership and the education community to promote the importance of vaccination to support schools remaining open and/or opening safely
Use every opportunity to educate about routine vaccinations39
∘ Clinicians and health systems should use every opportunity to educate parents, caregivers, and patients about the importance of routine vaccinations, including when patients are administered a COVID-19 vaccine. This includes scheduling vaccination visits and providing a high-quality recommendation.
Utilize centralized reminder recall40
∘ Communicate with state public health officials and medical societies about utilizing centralized reminder recall systems to send e-mails, text messages, patient app notifications, and mailings to patients for routinely recommended and catch-up vaccinations in an effort to bring individuals in for their vaccinations now
Elevate trusted voices for vaccination33,38,41
∘ Identify organizations, parents, and youth voices in the community to highlight the drop in routine vaccination and highlight the need to return to care
Expand access points to vaccination services to help “meet people where they are”3,38
∘ Plan vaccination sites at schools, drive-through clinics, and mobile vaccination clinics
While short-term strategies are necessary to mitigate effects now, long-term systems-strengthening measures must also be implemented to develop a resilient immunization ecosystem. Long-term strategies that may help with systems strengthening include:
Enhancement of immunization information systems42
∘ Strengthen IIS by (1) ensuring timely and complete exchange of data; (2) enabling IIS to collect data across the lifespan; and (3) dedicating sustainable financing to support IIS maintenance and enhancement
Mitigate barriers to vaccination43
∘ Ensure policies, both at the federal and state level, support access to vaccination services. This includes mitigating direct costs to the patient such as eliminating out-of-pocket costs for vaccination services, as well as indirect costs to the patient such as providing transportation reimbursement for medical services such as vaccination.
Secure sustainable funding for immunization infrastructure
∘ Identify and address inefficiencies in vaccination financing and use of resources, while exploring innovative policies to secure financing for sustainable, resilient, vaccination programs
Invest in building vaccine confidence33
∘ Build a strong understanding of the underlying drivers for vaccine hesitancy and strengthen local capacity to manage issues related to vaccine hesitancy while building trust in science, public health, and health care professionals
CONCLUSION
As the country continues efforts to end the COVID-19 pandemic, including through COVID-19 vaccination, it is critical to remain vigilant in efforts to support routine vaccination. Routine vaccination programs require both immediate actions to recover coverage rates, as well as long-term efforts to build back stronger and protect communities from vaccine-preventable diseases in the future. Recovering vaccination rates will continue to necessitate cross-sectoral collaboration to address the COVID-19 pandemic while ensuring individuals remain up to date with CDC-recommended vaccinations.
